Used as an intermediate in organic synthesis, particularly in the preparation of liquid crystal materials for display technologies. Its structure supports the formation of stable mesophases, making it valuable in the development of advanced liquid crystal compounds. Also employed in cross-coupling reactions, such as Suzuki and Heck reactions, to build complex aromatic systems for pharmaceuticals and agrochemicals. Its bromo and ethyl functional groups provide sites for further chemical modification, enhancing its utility in research and industrial applications.
